In the present study, we have employed site-directed mutagenesis to probe the role of four residues in E. coli ProRS (Ec ProRS) on the overall catalytic function. Specifically, we examined the impact of changes in amino ...

All living organisms contain amino-acyl tRNA synthetases (AARSs) ‒ a family of enzymes critical for protein synthesis. They are responsible for the covalent ligation of proline to its specific tRNA molecule, called tRNAPro, ...
